Electrochemical machining (ECM). is a machining process in which electrochemical process is used to remove materials from the workpiece. In the process, workpiece is taken as anode and tool is taken as cathode. The two electrodes workpiece and tool is immersed in an electrolyte (such as NaCl).
ElectroChemical Grinding, or ECG, is a variation of ECM (ElectroChemical Machining) that combines electrolytic activity with the physical removal of material by means of charged grinding wheels.
The protruded diamond particles continually remove any passive layer that may be formed on the surface of the workpiece by chemical or electrochemical action, and also determine the form of the workpiece, as is the case in conventional grinding.

Abstract. This paper reports the development of the mathematical modeling of an abrasive electrochemical grinding (AECG) process. In AECG a metal-bonded grinding wheel is used instead of a graphite or metal wheel-electrode used in electrochemical grinding (ECG).
Electrochemical grinding is a process that removes electrically conductive material by grinding with a negatively charged abrasive grinding wheel, an electrolyte fluid, and a positively charged workpiece.
In this case, with the demand for electrochemical grinding, it is also used as an electrolyte. WGR pitch distance is 320 μm and the diameter of wire is 120 μm, and the size of SiC is less than 15 μm, hereby the thickness of the wafers is about 180 μm.
Everite is excited to announce our first ElectroChemical grinding machine installation in Saudi Arabia. Everite technicians travelled to Saudi Arabia in August to install our largest ECG Vertical Grinder, model VG1000, standing at over 12 feet tall and over 12 feet wide, this machine weighs 44,200 lbs.
Following are the application so the electrochemical grinding that you must know: This process is used for the materials that are very hard such as stainless steel. In case of harder materials, it removes the metal 10 times faster and smoother than the traditional machining process.

ElectroChemical grinding, or ECG, is machining that combines electrolytic activity with the removal of material through charged grinding wheels, producing burr/stress-free parts. It was the need for burr-free grinding that led a propulsion firm in the Middle East to seek Everite’s help.
It can be seen that in the case of electro-chemical smoothing, maximum height of surface irregularities is Rmax = 0.05 m m., i.e. same as the initial value, and in the case of mechanical grinding this height decreases to Rmax = 0.008 m m., while with the combination of both processes it is possible to achieve Rmax = 0.006 m m.

Six different processes can be used to produce micro threads: tapping, conventional turning, thread chasing, thread rolling, grinding and electrochemical grinding (ECG). Thread chasing and thread rolling are performed on lathes, with tools other than a conventional v-groove tool.
The Burr Free Electrochemical Grinding process is a hybrid method of metal removal combining Abrasive Grinding and Electrochemical Machining (or ECM). ECM is a non-traditional metal removal method developed many years ago based on Michael Faraday’s laws of electrolysis.
